A reference to a child in a realm. This struct will be returned when a child is added to a
realm, and may be used in subsequent calls to RealmBuilder or SubRealmBuilder to reference
the child that was added.
A reference to a collection in a realm. This struct will be returned when a collection is added to a
realm, and may be used in subsequent calls to RealmBuilder or SubRealmBuilder to reference
the collection that was added.
A controller used to influence and observe a specific execution of a component. The component
will be stopped when this is dropped if it is still running from the start call that created
this controller. If the component has already stopped, or even been restarted by some other
action, then dropping this will do nothing.
The RealmBuilder struct can be used to assemble and create a component realm at runtime.
For more information on what can be done with this struct, please see the documentation on
